Beyonce is losing out on hours of beauty sleep – because she’s addicted to staying up late and watching fans perform her famous dance moves online. (My all time favorite fan version is the one above)

The success of Knowles’ catchy tune Single Ladies (Put a Ring on It) blew up when the star shook to the beat in her new music video, wearing only a body-hugging leotard and high heels.

The singer found her inspiration after stumbling across a clip of a 1960s Bob Fosse routine called Mexican Breakfast on video sharing website YouTube.com.

And now she can’t stop surfing the net for spoofs.

She tells U.S. magazine OK! “It’s beautiful, it’s amazing and I love it! I stay up all night watching them.”
